HOL-DER FOR SPINNING-RINGS.

SPECIFICATION forming part of Letters Patent No. 370,234., datedSeptember 20, 1887.

Application filed DOCOIDLOI'4, 1886. Serial No. 220.649.

To all whom, it may concern.-

Be it known that 1, JOHN BOOTH, of Central Falls, in the State of RhodeIsland, have invented certain new and useful Improvements in Holders forSpinning-Rings, of which the following is a specification.

My invention relates to devices for fastening rings to the ring-rails ofspinning-machines and for supporting the former on the latter, andparticularly to such devices as are designed to support and secure areversible or duplex race ring in position on the ring-rail.

It is the object of my invention to provide improved means for securelyfastening the ring in position, and which will at the same time permitof its ready removal and replacement for the purpose of reversing itsposition on the rail, repair, &c.

It is also the object of my invention to provide means for supporting aring which may happen to be smaller than the hole in the ring-railthrough which the bobbin or spindle extends in proper position on saidring-rail.

It is also the object of my invention to provide means, in connectionwith those hereinbefore set forth, for adjusting or centering the ringwith respect to the bobbin or spindle.

My invention consists in a ring'retainer formed as a segment orsubstantial half of an annulus flanged at its inner edge so as to lapupon the race of the ring substantially halfway around the same, or fromone side around to the opposite side, the construction and relationshipof the parts being such as to permit the ring to be freely slipped intoplace under the flange of the retainer or withdrawn therefrom, as alsoto be moved laterally, in order to center or adjust it with respect tothe spindle or bobbin.

My invention also consists in certain improvements incidental to theforegoing, all of which I will now proceed to describe and claim.

Reference is to be had to the accompanying drawings, and to the lettersof reference marked thereon, forming a part of this specification,similar letters indicating corresponding parts.

Of the drawings, Figure 1 represents a perspective view of a portion ofaring-rail having a ring secured thereto in accordance with my (N0 modl.)

invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is aview similar to that represented in Fig. 2, and showing in addition myimproved ring-supporting device. Fig. 4 is a top plan View of a portionof a ring-rail and my improved means for directly supporting the ring.

So far as my invention relates to contrivances for securing a ring inposition on the rail it is an improvement upon the device discovered inthe patent to J. H. Sawyer, No.1l7,934, granted August 8, 1871. In saidpatent is shown a split ring provided with a flange, which split ringwas adapted to be sprung upon or over the lower race of thespinningring; but in order to so connect the latter ring with the splitfastening-ring it is necessary to remove said split fastening-ring fromthe rail and exert considerable force or pressure, occasioning troubleand loss of time, not to mention the liability of so bending orspringing the split fastening or retaining ring out of position as toimpair its usefulness.

By my improvements the objections attending said patented device areovercome in the provision as a ring retainer or fastener of a segment orsubstantial half of an annulus. (4, having a flange, 1), formed on itsinner edge, which flange is adapted to extend over and be clamped uponone of the races 0 c of a revisible or duplex race-ring, A.

(Z d represent slots formed in the sides of the ring-securing device a,for the reception ofthe shanks of the screws 0 6', adapted to be screwedin the ring-rail \Vith the devices constructed as hereinbcforedescribed, the ring can be slipped sidewise between the ends 9 g of thering-securing device, under the flange b of the san1e,thc screws 6 0turned down, and the ring held in position with entire security.

Should it be desired to remove the ring to reverse its position, allthat is necessary is to slightly loosen the screws 0 6, when the ringmay be moved laterally out from the securing device between the ends 1g, and the desired manipulation of said ring accomplished withoutunnecessary consumption of time, strain of the parts, or the removal ofthe securing device from the ring-rail.

Slots (1 d being larger than the shanks ofthe screws e e, provision ismade for adjusting or centering the ring with respect to the spindle orbobbin.

To provide forsupporting rings upon a ringrail having holes for thespindle or bobbin larger in diameter than the ring, I construct awasher-plate, h. of substantially the same -form' as the securing devicea, which plate h is adapted to rest on the upper face of the ringrailfand extend over a portion of the hole formed in the latter, forming theimmediate rest or seat for the ring, the washer-plate resting on the topof the ring-rail, as clearly pictured in Figs. 3 and 4. Rings of varyingdiameter may be thus applied to old frames without regard to thediameter of the holes in the ring-rail, and by my improved securingdevice the ring can be held perfectly level and rigidly to the rail, andbe at the same time easily and quickly removed, as before described, forthe purpose of reversal, repair, or exchange.

- The ring-retainer a being constructed as a substantial half of anannulus, the flange b is made to lap on the lower race of the ringsubstantially halfway around the same, or from one side around to theopposite side, and in this way hold the ring at the rear as well as atthe sides, so that a tap or blow accidentally given to the ring infront, where it would be likely to fall if it occurred at all, would notdisplace the ring. Furthermore, by a slight loosening of the screws 6 e,the ring may be readily adjusted on the rail, or removed, reversed, andreplaced, and itis not necessary in centering the ring to give anyattention to the securing device further than to turn down the screws 6e.

I am aware that it has been proposed to se cure rings to ring-railsbyaplurality of clamplike holders, each composed of a base extendingunder the ring and between the same and the ring-rail, said base havingan upturned hooked flange, which extends upward and over the interiorportion of the race, and a separate plate adapted to bear on theexterior portion of the race, with a screw to secure each holder inposition. The objections to this construction are, first, that itobstructs the interior area of the ring, interfering with the spinningoperations and the doffing of the bobbin; second, that it consumes muchtime in securing a proper centering of the ring, by reason of thedifficulty of holding and manipulating the several parts of the device,since the position of each of the several clamps, as

- well as that of the ring itself, must be seen-to at the same instant,and, third, that it does not provide a firm support for the ring or ameans for the ready removal and replacement of the latter. Theseobjections are entirely overcome by-my improvements in that the interiorarea of the ring is left free and unob structed, the ring is firmly andsecurely held in position and against accidental displacement, and, ashas already been remarked, by a slight loosening of the screws e e thering may be readily removed, reversed, and replaced, and in centeringit, it is not necessary to give any attention to the securing devicesfurther than to turn down the fastening-screws e e.

, Having thus described my invention, what I claim is- 1. The ring-rail,a duplex race-ring, the ring-retainer a, constructed as a substantialhalf of an annulus, having a flange, b, at its inner edge, adapted tolap upon the lower race substantially half-way around the same, or fromone side of the ring around to the opposite side, and screws forsecuring the ring-retainer and through the latter the ring to the rail,all combined substantially as and for the purposes hereinbefore setforth.

2. The ring-rail, a duplex race-ring, the ring-retainer a, constructedas a substantial half of an annulus, having a flange, b, at its inneredge, adapted to lapupon the lower race substantially half-Way aroundthe same, or from one side of the ring around to the opposite side, andprovided with slots (1 d, and fastening-screws e c, said slots beinglarger than the shanks of said screws, to permit of the lateraladjustment of the ring, all combined substantially as and for thepurposes hereinbefore set forth.

3. The ring-rail, a duplex race-ring, and the ring-retainer a,constructed as a substantial.

half of an annulus, having a flange, b, at its inner edge, adapted tolap upon the lower race substantially half-way around the same, or fromone side of the ring around to the opposite side, in combination withthe washerplate h, adapted tobe interposed between the ring andring-rail, and the fastening-screws e e, substantially as described.

In testimony whereof I have signed my name to this specification,inthepresence of two subscribing witnesses, this24th day of November, 1886.

JOHN BOOTH.
